How Do You Secure Your Wifi When Working From Home?

There are a lot of organizations that still use password and single loggin. Woter, how do what are your barriers in implementing multifactor ontenpication? There was even niation, i believe, inn the energy sector that got hacked because they were using the same password over the different systems. For example, i am someone who loves to be creative, who doesn't really like to do a, b, c, d in that order. So for me, i had to put in place coping mechanisms. And processes, support me adopt that behaviour. For some one else it must can be much easier.
